dow control mechanisms, andit .is the object of resilient material,preferably rubber,v that ot the invention to provide a roller formedV,will secure a `perfectly noiseless.operation and act to lcushionvibration, shocks orjars to which the mechanism may besubjected;

In the drawings: f Figure l is a view in sectional elevation of avehicle window of the vertically 'slidf able type showingTv a controlarm engaged with said window by means of the improved roller; V

Figure 2 is an axial sectional view of said roller. I

lIn these views, the reference character 'A designates a verticallyslidable window mem ber' consisting preferably 'of .an unframed plate ofglass, one of the slideways being indicated at B, saidslideway beinggrooved as indicated at B to engage a vertical edge of the glass.Thebottom edge ot the? plate A.

is embraced by a sheet metal` channel strip. y

C, and a sheet vmetal runway D orfthe roll er is secured tothe strip Cprojecting downyl Y Y member, vof, a run-way secured to 'an edge wardlytherefrom. ylheroller which' is indicated at E is journaled upon-the'upper end of a control arm F, and 1s formed ywith an annular grooveinwhich the channelstripC' is adapt-ed to seat. fVVhen said roller isproperly vengaged beneath the glass plate A,

a cylindrical side portionE D formed upon the lower edgeof said runwayprojects rbeneath the cylindricalface' E of the roller, maintaining thedescribed engagement of the roller with the* channel, C, and receivingthe down 'thrustpot the roller when the control arm Fis being employedto lower the plate A.' The 'roller vE is formed ot an'elasticshockfabsorbing maa terial, preferably rubber. To rotatably mount saidroller upon the armF a bushv ing G may bc axially arranged within theroller to torni a bearing-rotatively.engage-f.

Furthermore, said roller. functions as avshock absorber to take To give-said bushing retention with re spect tothenrol'ler, itis preferred to flange kone end ot the bushing outwardly,as indi-' cated at I, vand yt0 formy a` short cylindrical flange I'at'the outer'edge ofthe flange I, n the flangesI and I being` embeddedin thek v roller. The pin Hl is .formed with a head the roller asv athrustbearing. 1

W hat'I 'claim as my invention is: 1. The combination with av slidingwindow member and a Acontrol arm for actuating said window member, ofashock absorbing element' carried yby said arm and engagedwith saidwindow member to operate theV latter from the former.

2.` The combination with a sliding windowV 'l so portion of said windowmember land a roller having. -a portion engagedl in said runway, saidroller being adapted Vto alternatively bear in voppositedirections `uponsaid runway and window member to actuate said window memberalternatively in opposite direc-V tions and'said roller being formed 'ofyieldable material to absorb the shock of its contactwith said run-wayand window member.

3. Thel combination with a sliding window member, of a. run-way securedto an edge portion-ofV said window member and Ahaving a flange-spacedtherefrom, and" a roller formed of yieldablematerial and engaginginsaidrun-way. 4.* The combination of a sliding window,

" a control arm 'for actuating' said window,

and shock labsorbing means for Operating the wlndowfrom the arm,Including Aa vrunway member secured to the window and aV `transversemember secured to the arm, one

of said membersbeing resilient to absorb the Y shock of its contact'withthe other of said members. f f 'In testimony WELLS W. CARROLL. Y
